Hi @mlinodasilva,

If you're willing to check Ubuntu Touch OTA-15 out again, I want to know why you're receiving this permissions error. Maybe you can send me a private message on the forum when you're available and we can try to debug a little faster? Then we can post any results back to this thread.

@mlinodasilva
Glad you found the answer on your own.
Sadly Meizu pro5 is difficult to find hence a smaller community here.

And it's hard to help when you cannot reproduce the issue.
